Adapter kit Mitsubishi 4G63 - BMW M50 S50 M52 S52 M54 ZF-5 5-speed - 240mm / 9.45"

PMC Motorsport adapter / conversion kit / clutch kit Mitsubishi 4G63 – 5-speed manual BMW M50 M52 M54 ZF-5 ZF310 ZF320 Getrag S5D-250G / 6-speed Getrag 420G S50 – 240 mm / 9.45"

Adapter kit allowing connection (swap / conversion) of the Mitsubishi 4G63 engine with the 5-speed manual gearbox ZF-5 (ZF S5D-310 / S5D-320) or Getrag S5D-250G used in BMW with M50 / M52 / M54 / S50 / S52 engines, as well as the 6-speed Getrag 420G gearbox from BMW E36 M3 (S50). An ideal solution for amateur and professional motorsport.

Planning a Mitsubishi 4G63 swap in your BMW (E30, E36, E46, E34, E39, E90, E91, E92, E60, E61, E81, E82, E87)? Our adapter is a reliable solution. Swap your automatic transmission for a manual BMW gearbox and unlock new possibilities.

PMC Motorsport adapters not only enable automatic to manual gearbox conversion in vehicles with the Mitsubishi 4G63 engine, but also support completing 4G63 swaps in BMW as well as other vehicles such as Nissan (S13, S14, S15, PS13) or Mazda RX-7 / RX-8.

Aluminum gearbox adapter designed to simplify gearbox installation as much as possible without radical modifications like cutting off the bellhousing – only preparing a cutout for the starter motor is required. Custom flywheels dedicated to PMC Motorsport adapters are made of aluminum with a replaceable friction surface, tested and balanced before shipping. Flywheel designed for 240 mm pressure plate (BMW M57 / M57N / M57N2 / N54 / B58 / E46 M3 OE).

PMC Motorsport gearbox adapters are synonymous with precision and top quality. The design process based on 3D scanning and inspection using a measuring arm ensure a perfect fit. Production on modern CNC machines guarantees ideal concentricity of the engine and transmission, which is crucial for the durability of the drivetrain.

Additional information

Installation instructions

A BMW M50 / M52 / M54 OE starter motor is required for the installation of the adapter and flywheel (not included) – OE numbers available in the FAQ section.

In ZF-5 (ZF 310 / ZF 320) and Getrag 250 / 420G gearboxes, the two upper holes in the gearbox housing (bellhousing) must be slightly grinded – this modification does not affect the centering of the engine and gearbox.

Release bearing, clutch release fork, and slave cylinder are not included in the kit: BMW OE release bearing 21 51 7 521 360 (1-position) or 21 51 7 570 154 (2-position), BMW OE clutch release fork 21 51 1 223 302 (1-position) or 21 51 7 564 027 (2-position), BMW OE slave cylinder 21 52 1 164 529 (Ø 23.81 mm).

Frequently Asked Questions

Which engines does this adapter fit?

For Mitsubishi 4G63 engine in the 7-bolt flywheel mounting version (engine contour according to 3D scan of Mitsubishi Outlander CU_W).

Which gearboxes does the adapter fit?

For 5-speed ZF-5 (ZF S5D-310 / ZF 310 and ZF S5D-320 / ZF 320) and Getrag S5D-250G gearboxes from BMW with M50 / M52 / M54 / S50 / S52 / S54 engines (including E36 328i, E46 328i / 328Ci / 330i, E34 525i, E39 525i / 528i / 530i, Z3 2.8i / 3.0i), as well as the 6-speed Getrag 420G (TBAB, TAGU) gearbox from BMW E36 M3 (S50). Flywheel does not fit BMW M54 6-speed manual gearbox.

Do I need to cut the gearbox bellhousing?

No. The adapter is designed to avoid cutting the bellhousing – only a cutout for the starter motor needs to be prepared.

Does the ZF-5 / Getrag gearbox fit into all holes of the adapter?

The PMC Motorsport adapter is the most universal adapter available on the market, supporting virtually every BMW gearbox. When designing it, we decided on a slight compromise – in Getrag 250 / Getrag 420 / ZF 310 / ZF 320 / ZF-5 gearboxes, the two upper holes in the gearbox housing (bellhousing) must be slightly grinded. This modification does not affect the centering of the engine and gearbox.

Which starter motor should be used?

BMW M50 / M52 / M54 starter motor, OE 12 41 2 354 709 (2354709) / 12 41 1 740 379 (1740379) / 12 41 2 344 247 (2344247) / 12 41 1 740 378 (1740378) / 12 41 1 740 375 (1740375) / 12 41 1 738 602 (1738602) / 12 41 1 466 102 (1466102) / 12 41 1 712 937 (1712937) / 12 41 1 735 524 (1735524) / 12 41 1 738 604 (1738604) / 12 41 1 715 238 (1715238). Starter motor is not included in the kit.

Which clutch pressure plate fits the PMC flywheel?

240 mm (9.45") BMW OE type pressure plate – from BMW M57 / M57N / M57N2 / N54 / B58 / E46 M3 or Sachs Performance 883082.001243. Clutches from ACT / Spec / Tanaci are also often used – custom pressure plates must fit the BMW OE flywheel (M57 / M57N / M57N2 / N54 / B58). For the ZF-5 gearbox, use a 240 mm clutch disc with 23x29-10N splines, a dedicated release bearing kit, and a slave cylinder.

Can I use the adapter with a 6-speed GS6-53DZ / GS6-53BZ gearbox?

Yes. The PMC Motorsport gearbox adapter itself is universal and fits most BMW gearboxes (applies to adapters manufactured after 2022). In case of changing the gearbox, you only need to replace the flywheel and clutch disc.

Does the adapter also fit the ZF 8HP automatic transmission?

Yes. The PMC Motorsport gearbox adapter itself is universal and fits most BMW gearboxes (applies to adapters manufactured after 2022). When converting to a ZF 8HP automatic transmission, the standard flywheel must be replaced with the PMC Motorsport 8HP torque converter adapter.

Can I buy only the adapter or only the flywheel?

Yes. Every component of the kit is available separately.

Does the price include customs duty when shipping outside the European Union?

No. Product price and shipping estimate do not include customs duties or extra fees that may apply in the destination country.

Can I buy with 0% VAT?

Yes, if you are a B2B customer outside Poland with an active EU VAT number (verified in VIES) or ordering for export outside the EU.

Is the included manual enough for installation?

The manual describes joining the engine and gearbox outside the chassis. Depending on the car, extra modifications may be needed: mounts, bushings, firewall, transmission tunnel, driveshaft length. Professional installation recommended.

It is worth noting that a lightweight single-mass flywheel provides uncompromising throttle response at the expense of eliminating factory dampening elements. This results in a more direct drivetrain operation, which can naturally increase the noise generated by the gearbox mechanism. This is a desirable characteristic in sports vehicles resulting from the rigid engine-to-drivetrain connection.
